Extensions of previous experiments at high temperatures and high pressures in the laser heated diamond anvil cell and calculations involving the detailed pressure-temperature environment are to be carried out. The PI will reexamine the phase loops involving the transformation in the magnesium-iron silicate in the perovskite structure in both the olivine and pyroxene systems. The sharpness of this phase loop, the partitioning of elements among coexisting phases, and the Clayperon slopes of these reactions will be determined.

以前的高温实验的扩展， 激光加热金刚石砧座单元中的高压， 详细的压力-温度计算 环境是要落实的。 PI将重新检查 涉及镁-铁相变的相环 在橄榄石和钙钛矿结构中的硅酸盐 辉石系统 这个相位环的锐度， 元素在共存相之间的分配，以及 将测定这些反应的Clayperon斜率。
